EGG BEATER.

To all rwhom t may concern: i

Be it known that I, ALEXANDER BnvAN, a citizen of the United States, andresident of the city `of Providence, in the county .of`

Providence and State of Rhode Island, have vinvented certain new anduseful Improvements in Egg Beaters, of which the followino is aspecification.

has for its object to provide an improve-` ment in this class of beatersin which two beater members are employed to `rotate in oppositedirections about a common axis, the beating surfaces of the beatermembers beingso disposed as to be readily accessible to be cleaned andso kept sanitary. The nature and advantages of the invention will bebetter understood when the following detail description is taken inconnection with the accompanying drawings,

y the invention residing in the combination and arrangement of parts asclaimed.

In the drawings forming part of this specification, like numerals ofreference indicate similar parts in the several views and where- Figure1 is a side elevation of my improved beater. v

Figure 2 is a detail of the outer frame supported in vits bearingmember. y

Figure 3 is an end view of the beater frame `bearing member.

Figure 4: is a side elevation of the driving shaft and the inner beaterymembers connected thereto.

It is found in the practical use' of egg beaters thatthe beater membersare pivoted at their lower ends to a frame or* the like this pivot formsa stop or barrier and so prevents or interferes withthe ready andperfect cleaning of the working portions thereof and when the materialinto which the beater is inserted, is not entirely removed it decomposesand so renders the device unsanitary To obviate this objectionabledifliculty I have so constructed my improved beater that the beatermembers are supported only at their upper portions above their beatingsurfaces; their lower or working portions being spaced from the frameand from each other to permit unhampered cleaning between them.

The following is a detail description of functions of my invention, inwhich 10 designates the frame portion thereofwhich is preferablyconstructed of wire having two side members 11 spaced 'apart and setparallel with each other for a portion of their length, to form a handleportion 12, the lower portion 13 of this frame being en- Y l larged toinclose the beaters, and the lower lhis invention relates to leggbeaters, and

cross-barV 14: ofwhich is adapted vtorest uponrthe bottom of thereceptacle in which the material to be beaten, is held. i y l The sidesof the frame are held inspaced apart relation by means of yupper andlower bearing cross-bars 15 and 16 and are bound together by means ofthe binding plates `17, the side edges 18 of which are rolled over saidside frames.

In these bearing bars is mounted a vertically-disposed driving shaft 19,its upper end being provided with a driving pinion 20, and its lower endwith a coupling or sleeve 21 into whichthe upper end of the smaller orinner beater frame membe`r122is fixed so that this beater member iscaused to rotate inunison with this shaft. l

f Loosely mounted on "this shaft above this coupling member isv abearing member or hub 23, .its upper end'being provided with n adrivinggear 24C and ther body portion of this bearingmember is slottedlongitudinally at 25 on opposite sides to'receive` the spaced'apart side"arms 26 of the wire outer beater frame 27.

These arms are preferably indented as at 32 to fit into correspondingrecesses 33 in the slots 25 and "when these arms are positioned in theseslots they are locked therein by a collar or ferrule 28 which is forcedover the same about the bearing member to `bind and releasably securethese arms in their slots; it being only necessary to remove thisferrule when it is desired to detach this frame from its hub.

Ini order to impart a rotating motion to theshaft 19 Aand its innerbeater frame 22 ink one direction, and the bearing member 23 with itsouter beater frame in the opposite direction, I have mounted a largedriving gear 29von the pin 30 in the binding pla-te 17, which gear isprovided with-a suitable handle 31 by which it may be rotated.

Bythis construction it will be seen that the inner and outerframe-shaped beater members are mounted to rotate one within the otherboth about a common axis and also separated from the frame Which in-rthat both of these beater members are separated from eachother atallpoints and are the outer supporting traine. No lower pivot or bearingbeing provided to prevent such cleaning action.

In some eases instead of making the side f members of the Wire beatingiframes straightl as illustratedy in Figures 2 and 4,

I .so bend the sides ofl these frames inwardly as at Bland 85, that theywill inter-f lock one with the other thereby rendering more effectivethe beating action.

`My improved device is extremely simplel and practical -`in constructionand eective yin its operation and lby the improved jai rangement of itsparts it maybe readilyy and thoroughly cleaned thereby rendering itperfectly sanitary. ,i L

` The foregoing description is `directed solely towards the constructionillustrated,

- butI desire it to' be understood that Ireserve the privilege ofresorting to all the mechanical changes to Which the device issusceptible, lthe invention being defined and limited only, by the termsof the appendedl claims. f s, y,
